  Reference numeral 80 denotes a handle, which is formed from a through-hole formed in the upper portion of the body portion of the container body 1.

Next, the operation will be described.
FIG. 1 shows a state before the engagement of the mounting member mounted on the container body neck 3 is released. When the contents in the container body 1 are consumed and become empty, the mounting member is removed from the container body neck portion 3 and replaced with the refill container 90.

  In order to remove the mounting member from the mouth-and-neck portion 3 of the empty container body 1, it is only necessary to pull up the disengagement portion 50 via the finger hook portion 60, and then the placement cylinder 56 is separated upward from the container body shoulder portion 3. At the same time, the engaging cylinder 53 and the sliding cylinder 52 rise.

  Since the second inclined portion 54 provided in the engaging cylinder 53 is slidably engaged with the first inclined portion 46 provided in the elastic leg portion 44, the elastic leg is raised when the engaging cylinder 53 is raised. As the portion 44 gradually expands and the second protrusion 45 is disengaged from the first protrusion 4, the lower end of the elastic leg portion 44 enters the gap between the engagement cylinder 53 and the sliding cylinder 52.

When the second protrusion 45 is detached from the first protrusion 4, the lower end of the elastic leg portion 44 comes into contact with the bottom of the gap between the engagement cylinder 53 and the sliding cylinder 52, and the lower end of the drooping cylinder 12 is outside. It contacts the upper surface of the orientation flange 55. Thereafter, the base 10 is pushed up with the rise of the engaging cylinder 53 and the sliding cylinder 52 and is disengaged upward from the mouth-and-neck part 3.

  In order to attach the mounting member removed from the empty container body as described above to the refill container 90 shown in FIG. 4, the hanging cylinder 16 may be inserted into the mouth and neck portion 3 of the refill container 90. Then, the elastic leg 44 expands while the second protrusion 45 gets over the first protrusion 4 and the upper surface of the second protrusion 45 engages the lower surface of the first protrusion 4. Return to shape. As described above, since the elastic leg portion 44 is engaged with the outer surface of the mouth and neck portion 3, the base portion 10 does not come out of the mouth and neck portion 3 even if hydraulic pressure acts on the hanging cylinder 16 at the time of pouring.

In the above description, a pouring member in which the bowl-shaped nozzle 30 is erected from the bottom wall of the hanging cylinder 16 is used. However, the present invention is not limited to this. For example, application for application instead of the pouring member is performed. A member may be provided in the mouth-and-neck portion 3, or the dispensing member or application member, the auxiliary cylinder 20 and the cap 70 may be omitted, and a cap may be attached to the upper end of the cap fitting portion 17 via a hinge. Is possible.
